I go back and forth and desperately trying to justify going clipless after 40 years of platforms. About once a month I reopen the almost healed road rash on my elbow from tipping over again.

Just rambling here but from my personal experience.
I've ALWAYS been a ~ 60 RPM person, large hills, on road, off road, standing, sitting, climbing, no hills, it didn't matter. Been riding like that for decades and I am just used to, tuned for it, built for it, and comfortable with it.. Recently... My knees are becoming a bottle neck so I am relearning and forcing myself to ride at 75-100. It is not easy for me and a whole different experience. Different things getting tired and weak at different times than before as I now do higher speed circles with less pressure on the pedals instead of low speed well planted pushes. In my perfect world, I can still stay with platforms and turn higher cadence but we'll see how it pans out as I try different things including slowing down.
